"Out of 60,334 of these route pairs, Haque says that switching mid-route for 4,666 of them could save at least $1 together. Further, he suggests that companies like Uber and Lyft might one day play the app middlemen and allow riders to swap routes by smartphone if future tickets go digital. This, he writes, might force "monopolistic" public transit systems to become more efficient by eliminating the possibility of route swapping--like by charging a flat rate per trip, as New York City’s Metropolitan Transit Authority does." - × × ×
